Water samples were taken at three different locations in a river to determine whether the quantity of dissolved oxygen, a measure of water polution, varied from one location to another. The results are given in the table below.
1 2 3
5.6 6.1 3.8
6.3 6.7 3.5
5.2 6.5 3.9
5.8 6.3

If we were to use ANOVA to analyze this data, what would be the value of SS(treatment)?

Answer #1

We can directly use here one way anova by Excel.

Step 1 ) Enter data in Excel.

Step 2) Data >>Data analysis >> One way anova >>Select data >>click on label in first row >>ok

SS(treatment) = 12.74765

The quantity of dissolved oxygen is a measure of water pollution in lakes, rivers, and streams. Water samples were taken at four different locations in a river in an effort to determine if water pollution varied from location to location. Location I was 500 meters above an industrial plant water discharge point and near the shore. Location II was 200 meters above the discharge point and in midstream. Location III was 50 meters downstream from the discharge point and near...

We wish to determine the impact of Specification Buying, X11, on Satisfaction Level, X10. To do so we will split the Hatco data file into two separate data sets based on the Specification Buying, X11. This variable has two categories: 1=employs total value analysis approach, evaluating each purchase separately; 0 = use of specification buying. Sort the entire Hatco data set based on Specification Buying. This will create two separate groups of records. Those records with X11 = 0 and...
